The Chelsea 489 Series Power Take-Off, part number 489XFAHX-V5XQ or 489XFAHXV5XQ, is an 8-bolt PTO assembly built around a one-piece cast iron housing that bolts directly to the 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Mack, and Tremec. The 489 Series carries the same 250 lb-ft intermittent torque capacity as the Chelsea 442 Series and uses tapered bearings rather than needle bearings for greater load-bearing capability. The output shaft is a 1-1/4" round configuration with key, and shift actuation is wire/cable mechanical. Shaft power output is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Common internal parts with the 442 Series simplify stocking and service. Call us to confirm proper fit for your specific transmission and application.
